Authentication would be basic or digest (Personally I'm using basic
since it's - imho - a lot more compatible with clients)

From what I know the easiest way would be to have
http://public.example.com <- points to the publicly available part
https://secure.example.com <- holds all stuff that should be encrypted
Something to think of: With a single IP Address it's not possible (at
lost without investing money) to have different SSL Hosts on the same
IP. Apache will use the first SSL Host it finds to do encryption.
This is necessary since the client etablishes the encrypted
communication before even making a request.
So: https:/secure.example.com/part1, https://secure.example.com/part2
- where part1 and part2 could have totally different content.
Just direct your users to the secured subdomain and directory (if you
have the need for more than one), whenever they need to access a
could be done with
If you have only one directory (with only a single directory):
RewriteRule ^/secure https://secure.example.com/ [R]
More secured directories (this will redirect all subdirectories in
public.example.com to https://secure.example.com/$SUBDIRECTORY):
RewriteRule ^/(.+) https://secure.example.com/$1 [R]
Read a bit about some regular expressions how to get the correct

that is the module you need to enable, try a2enmod in a shell or man
a2enmod quite a convenient command...
hope that gives you a starting point
